A degradation-mode is a human-made classification of failure behaviors where a system responds to a fault by reducing its capability proportionally rather than ceasing operation entirely. Its parameters are: (1) the fault that triggers degradation, (2) the degraded capability level, (3) the conditions under which full function can be restored. It persists through engineering documentation, failure-mode analysis, and operational procedures. [formal: gradus | substrate: behavior | horizon: a moment | explicit: yes | epoch: 0.01]

Definition
Why it is in scope
A human-made categorization of failure behaviors — classifying how systems respond to faults by degrading gracefully rather than failing catastrophically. Built to persist through engineering practice, failure analysis, and safety-critical system design.

Degradation-mode is a design pattern where systems reduce capability proportionally rather than failing catastrophically. Its purpose is to maintain service under fault — it serves reliability. Per Law 8d: for-whose-sake test.
